The new Nseries devices let users work with music, video and images over the Internet, as single-purpose mobile devices have become less attractive to users, Nokia said.

The N76 contains a digital music player and 2-megapixel camera that can be operated while the phone is closed using buttons on the outside. With a 2GB microSD memory card, the N76 can hold up to 1,500 songs encoded by Nokia’s Music Manager software, or 250 songs encoded at a higher data rate by other software. It also contains Nokia’s Web browser software, and can send e-mail and instant messages. The phone should ship by March with a retail price of $507, Nokia said.

Nokia’s N93i is their new flagship blogging device, with a swivel head. It ships with a 1 GB miniSD memory card, which can store 45 minutes of DVD-like quality video in MPEG-4 VGA format. The phone also comes with video editing software, a 3.2 megapixel camera, and supports wireless broadband and streaming TV. Nokia said the phone should be released by March with a retail price of $780.

The N800 Internet Tablet performs faster and is better at keeping continuous Wi-Fi and Bluetooth connections alive than its predecessor, the 770, the company said. Based on the Linux open-source operating system, a software update will add VoIP capabilities later this year. Nokia and Skype will jointly develop software enabling the N800 to make and receive calls over the Skype VOIP service. The software should be released for download by June, the companies said.The N800 is available now in some European markets and the U.S. for around $399, Nokia said.
